The man accused of providing the intelligence that led to a controversial anti-terror raid in east London has denied he was the source.
Mansha was described in his court case as an "utter incompetent"
The lawyer of Mohammed Abu Bakr Mansha, 22, spoke out after some newspapers linked him to the operation in Forest Gate, in which one man was shot.
Mansha was jailed for six years in January for plotting to kill a soldier decorated for his service in Iraq.
He has now been put in segregation for his own safety, his lawyer said.
A man, subsequently freed, was shot in the Forest Gate raid which involved 250 officers.
Abul Koyair, 20, and his injured brother Mohammed Abdulkahar, 23, were arrested during the high profile raid on their Forest Gate home earlier this month.
They spent several days in custody but were later released without charge prompting a Metropolitan Police apology.
Now Mansha's lawyer, Sara O'Keefe, has hit back at media reports that he provided police with intelligence leading to the raid.
She said her client was concerned about the rumours and denied he was responsible for the information.
She said Mansha knew the two brothers from growing up in Forest Gate and that they had mutual friends.
Ms O'Keefe confirmed police had visited her client in prison but said that was not his choice and that he gave them no intelligence.
Mansha was jailed after London's Southwark Crown Court heard he had planned to kill or harm the soldier in revenge for his success in Iraq.
Cpl Mark Byles, 34, was awarded the Military Cross after leading an attack in which five insurgents died.
Mansha, of Thamesmead, south London, had denied a charge under the Terrorism Act.
He had earlier been convicted of possessing a document containing information likely to be useful to a person committing or preparing an act of terrorism.
After searching his flat police recovered a gun, newspaper cuttings about the soldier's exploits, and a stash of DVDs containing "virulent anti-West propaganda".
Mansha was described by his defence barrister as an "utter incompetent".
He is planning an appeal against his sentence next month.
